These valves should not be installed in systems that
exceed the ANSI specified temperature and pressure
ratings. Inspect the valves for shipping, damage and
foreign debris when uncrating.
Be sure to use proper hoists with chains or slings
when uncrating and handling these valves. Refer to
Table 1 in the data sheet for valve body weights.
1. Ensure the pipe is free from welding slag,
chips and other debris by blowing out the line
prior to installation.
2. Install approved gaskets between the valve
body and the pipeline flanges. For butt weld
ends on the Mark ET Series trim configuration,
remove gaskets and seal rings prior to welding
the body into the pipeline.
3. For continuous service applications, Jordan
Valve recommends a standard three-valve
maintenance bypass be installed. This
allows isolation of the valve body without
shutting down the pipeline system.
4. The valve should be positioned on the
line so the flow direction indicator
corresponds to the direction of flow in the
pipeline.
Note: The effectiveness of the pressure-energized
seal will be compromised if return flow exists
where the downstream pressure exceeds up-
stream pressure. The result could be leakage or
damage to the seal.
5. The valve body should be positioned with
the actuator vertically above it. It
is possible to position the valve with an
orientation below vertical with support
supplied for the actuator. Support for the
actuator is required if there is excessive
vibration in the line, or if the valve body is
positioned more than 45 degrees off
vertical.
